Suchosaurus (meaning "crocodile lizard"), originally believed to be a genus of crocodile, was later identified as a spinosaurid theropod dinosaur from Cretaceous England. The type material consists of teeth. Two species, S. cultridens and S. girardi have been named, though the S. girardi material was reclassified by Buffetaut as Baryonyx walkeri. The remaining species, S. cultridens, is known only from a single tooth that strongly resembles the teeth of the contemporary Baryonyx walkeri. While there are some differences between the teeth, these may or may not represent individual variation among specimens, and Suchosaurus may be a senior synonym of Baryonyx.
